Notes
1. VIO < VCC + 200 mV.
2. VIO and VCC ramp must be in sync during power-up. If RESET# is not stable for 500 µs, the following conditions may occur: the device
does not permit any read and write operations, valid read operations return FFh, and a hardware reset is required.
3. Maximum VCC power up current is 20 mA (RESET# =VIL).
